FASTENING DEVICE FOR PACKAGES.

Specification of Letters Patent. I

Patented Apr. 5,1921.

I Application filed'December 11, 1919; Seria1 No.34'4,26Q.

T 0 all'whom it may concern:

Be it known that I, HENRI Mourns, residing at Killingly, in the county of Windham and State of Connecticut, have invented certain new and useful Improvements in Fastening Devices for Packages, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an envelop or a fastening device for packages, and has for its object the construction of a simple and eiiicient, as well as a novel flap and tongue structure, which, when in position for fastening, cannot be unfastened without dee stroying the envelop or wrapper.

With this and other objects in view, my invention comprises certain novel combinations, constructions and arrangements of parts as will be hereinafter described, illustrated in the accom anying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a view in elevation of a wrapper or envelop, showing the primary flap in an open position.

Fig. 2 is a sectional view of my envelop in a closed'position.

Fig. 3 is a plan view of a wrapper or envelop constructed in accordance with the present invention, showing all of the flaps in an open position.

Fig. 4 is a fragmentary, perspective view of the primary flap, showing a modified form. of the tongue.

Fig. 5 is a fragmentary view of the wrapper or envelop, showing the tongue in the slit on the auxiliary flap.

Fig. 6 is a fragmentary, perspective view of the wrapper or envelop, looking at the outer side of the tongue, or-the opposite side of the tongue to that shown in Fig. 4.

Fig. 7 is a section taken on line 7-7, Fig. 1, and looking in the direction of the arrows.

Referring to the drawings by numerals, 1 designates the body of the wrapper or' envelop, and 22 the end flaps; the primary flap 3, as well as the auxiliary flap 1, is integral with the body 1. The auxiliary flap 4: is rovided with a longitudinally-extending siit 5, near its outer end.

The primary flap 3 is provided with a tongue 6. In the primary flap 3 is a transversely-extending slit 7, which slit 7 extends into the tongue 6, so that the tongue can be slightly compressed together at its middle (seeFig. 5) to allow it to enter the slit 5,

and after entering spring or expand to its paratively strong, and produce a hook that bears against the ends 11 (Fig. 5) of the slit portion 5, and by reason of the slit 7, the tongue 6 will have been expanded in the slit 5, so that the tongue 6 can not possibly be withdrawn from the slit without tearing the flap 4:. In the embodiments shown in Figs. 4 and 6, the same structure is involved as in Figs. 1 to 3 and 5, except that in this embodiment, I score or perfo rate, at 12, the tongue 6 so that the tongue can be easilytorn off the flat 3, when the wrapper, package, or envelop is tampered with. 7 V I While I have described the preferred emthe inner corners l0 ofthe tongue 6 combodiments of my invention, and have illus-.

trated the same in the accompanying drawings, certain minor changes or'alterations may appear to one skilledin the art to which this invention relates, during the extensive manufacture of the same and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.

What I claim is: r

1. In a device of the class described, th

combination of a body provided with a primary and an auxiliary flap, said auxillary' flap provided with a slit, said primary flap provided with a tongue, said primary flap having a slit extending into the tongue and terminating short of the outer edges of the tongue, said tongue provided with side wings, said wings provided with stiffening ribs extending the length thereof, and said tongue adapted to be slightly compressed for placing it in the slit of the auxiliary flap and permitting the inner ends of the wings and the ribs to hook under the ends of the slit of the auxiliary flap, substantially as shown and, described.

3. In a device of the class described, the

7 combination of a body provided with a primary and an auxiliary flap, said primary flap provided with a tongue, means on the tongue for permitting the same to be slightly compressed at opposite sides, and said tongue provided with wings having stiffening means, whereby when the tongue and wings are placed under a portion of the auxiliary'flap the tongue will be positively fastened under the auxiliary flap for preventing accidental or unauthorized opening I of the flaps.
